At this time, in the case of the secondary sealing part for sealing the cover film is attached to the deoxidant, a conventional sealing structure for sealing the film to the cup container can be applied, for example in the primary sealing part provided by the present invention It is possible to apply a press assembly consisting of only the configuration except the press block and the cutter.

Therefore, the cup container 100 containing the contents has a double sealing structure in which the primary sealing process is performed by the protective film 110 and the secondary sealing process is performed by the cover film 130 to which the deoxidizer 120 is attached. Therefore, since the contact between the deoxidizer and the contents is completely blocked, the contents can be prevented from being damaged, and the gas generated in the deoxidizer can be smoothly transferred to the contents of the cup container through the holes in the protective film. Freshness can be maintained and the contents can be effectively prevented from being altered.
